My (unpowered) subwoofer has only speaker wire connections (+ / -) but my reciever has only one rca output. how do I connect my sub? Thank you!!!
In order for this to work, you will need an external amplifier. Your receiver is set up to use a "powered" sub. With only speaker connections on the sub, it is a "passive" sub requiring a separate amp.

RCA output is stereo +- signal, you need to use the two RCA audio cables to connect the speaker, you may need to adapt a set of RCA audio cables to do this.
Use the RCA red and white cables, internal connector pin is + , external is -.
